T0 all whom it may concern.-

Be it known that I, HENRY SYMoNs, a subject of the Crown of Great Britain, residing at Totnes, in the county of Devon, England,

have invented a new and useful Improvement in Gas-Garburetors, of which the following 1s a specication, reference being had to the accompanying drawings.

The object of this invention is to provide an efficient apparatus which may be used by consumers of gas for the purpose of enriching the gas supplied to them by the gas-companies.

Figure lin the drawings is a central vertical sectional view of a carburetor constructed according to my invention. Fig. 2 is a vertical sectional view, on a larger scale, of a valve used in the carburetor and of the box for said valve and the passage which it controls.

B designates a cylindrical or other shaped vessel or casing, having at the bottom au inlet-nozzle, e, which is to be connected with the service-pipe or with a pipe from the meter.

j is aclosed annular reservoir, placed or provided insidethe casing B, to contain the oil or carbureting liquid, and having a central well, j', formed within its sides. The connection between the reservoir j and the well j is made by means of the pipe jz, in which a valve, j, is placed. This valve may be of any suitable form, but that shown in the detached View, Fig. 2, is simple and answers well the purpose. The valve-stem is attached to a float, jt, which floats in the liquid in the well j by its buoyancy, assisted by the spring 7'5, and will, so long as there is a sufficient quantity of liquid in the wellj, maintain the valve closed. The opening of this valve will be effected by means hereinafter described.

Fitted to the inletnozzle c is a tube, 7c, projecting upward into a second tube, 70, which rests on the carburetor B, and is closed at top in any convenient manner. This tube le is provided in its sides with vertical slits, which extend from a little above the level of the top of the reservoir j to the bottom of the tube, to permit of the gas passing in contact with the carburetingliquid. Round the tube 7c is fitted a cone, Z, which rests on a perforated galley, m, secured about half-way up, to the walls of the cylinder B.

Below the cone l is secured to the tube la by a :flexible connection, b, a wooden or other float, u, which is intended to iloat in the liquid in the well j.

Suitable openings, o, which may be covered with a light fringe, if desired, are left about the float for the gas to pass out. The space between the perforated galley m and the top of the cylinder is filled with silicate cotton or cottonwool, a mixture of charcoal and fibrous material, or any other suitable absorbent material.

The annular reservoir j is filled by means of the tube p, a smaller tube, p', being provided to allow for the escape of air during refilling, and also to serve as a guide for the gage-rod p2, to which the float p3 is connected. When the cap p4 is removed, this oat will rise to the top of the oil in the reservoir, :and the gage rod p2, bein g divided off or grad uated,will indicate the quantity of liquid in the reservoir.

The cylinder is closed by a cover, g, which may be screwed down to the top, so that it may be readily removed when it is desired to clean out the carburetor. Below the cover q a perforated funnel-shaped piece, q', is placed to prevent the silicate cotton, cotton-wool, or other solid material entering or stopping up the outlet t, provided in the cover for the egress of the earbureted gas. j

The quantity of liquid contained inthe well is just sufficient to keep the ioat a floating, and as evaporation takes place this float descends and rests on the valve-float, and by its weight opens the valve j3, thus allowing a sufficient quantity of-liquid to enter the well to again cause it to float. This operation is being continually repeated, and thus a fresh supply of liquid is always entering` the well.

It has been found, that, where a large surface of carbureting-liquid is exposed, the higher hydrocarbons pass off very rapidly, and the gas for a time is thereby enriched to a greater extent than is necessary, the enrichment of the gas decreasing in proportion as the evaporation of the lighter particles takes place; but by the means just described I obtain a regular and continuous supply of the lighter hydrocarbon vapors, which has a corresponding effect on the enriching of the gas. The gas passes up the tube 7c and down outside the same, and then passes through the slits in the tube 7o and the openings o in the float, and takes up the vapor from the liquid IOO before it passes through the silicate cotton or cotton-Wool or other material to the outlet t.

Provision should be made for the entrance of gas or vapor into the reservoir, to prevent the formation of a vacuum when drawing off the oil. v

The primary object of the silicate cotton or cotton-Wool or other material is to deprive the gas of any excess of hydrocarbon it may have taken up, but after a time the silicate cotton or cotton-Wool will become more or less charged with liquid, and it Will then also serve to supply any deficiency of carbureting-liquid to the gas, if required. Any excess of oil Will drain off from the cotton-Wool, silicate cotton, or other material and run back.

Having now described my invention and eXi plained the manner of carrying the same into effect, l claim- 1, The carburetin g apparatus consisting of a cylindrical or other shaped vessel containing a closed annular reservoir, j, for, oil or carburcting-liquid, Well jf, connectingpipej'i, valve arrangement ja j* j, tubes 7c c, cone l, galley m, flexibly-connected float n, iilling-pipe p, cover q, and perforated piece gf, all arranged substantially as herein shown and described.

2. In a gas-carbureting apparatus, the combination of the closed annular reservoir j, Well j', valve-connection jzjjtj filling-pipe p, airpi pe p gage-rodp2, oat p3, and cap p4, all substantially as herein shown and described.

3. In a gas-carbureting apparatus, the combination of the reservoirj, the Wellj, the stationary pipes 7c lc', ilexibly-connected float n', and valve-lioatj, substantially as and for the purpose sct forth.
